Saidstem 18 may ex tend througli'an opening in the arm and is l secured by a tgin 20. The arm 19 may also be clined or beveled holding surface provided wi I a sleeve 21 in which the stem 18 is guided and 'a spring 22 surrounding said sleeve between the arm 19 and the head 17, rovide suitable pressure -of the disk .for oldi the bottle, but permits the disk 16 to yiel upwardly preventing excessive pres-- sure on the bottle.

The disk is preferably made of wood and the under surface thereof is concaveas shown sit-2B to fit, and-securely hold the neck of thebot'tle. vIt will ,be seenv that with this construction a disk when worn may be readily removcdiand replaced while the machinesin in. operation.-.- .It is found in practice that the wooden-disks are particuiarl "adapted for the -present purpose,

The rock arm .19 is mounted on a rock shaft 30 arranged for rotative and end-wise move silent inthe bracket 11.

The lower'portionof t e roc shaft 30 consists of an enlarged clindrical portion 30' which is rotative in t end-wise movement therein b means of a pm br cam roller 34 secure the rock shaft and movable transversely m a transe cylinder 32,' but held against relativeverse slot 35 formed in the sleeve 32. The a roller 34 also extends through a cam slot in the extension 31, which slot comprises a vertical section 36 and an inclined tion 37.

The movements of the rock shaft 30 are controlled as hereinafter explained by a cam 38 formed on a bracket 39 secured to the stationary frame 40 of the machine. The shaft '30 comprises telescopic sections 42'and43 permitting its le h to be adjusted, said sections bein locke in adjusted position bya pin 41. T 1e upper section 42 is cut away on.

opposite sidesto produce flat surfaces, the section 43 havini; a correspondingly shaped ative rotation of said sections is prevented. A coil spring 44 is mounted on the section 43 betweena collar 45 thereon and a cap46 on the up )er end of the sleeve 31 and holds the roller 4-1 up against the cam 38. V

The arm 19 is provided with a bifurcated head 47 to receive the shaft section 42, and is ad justablelcngthwise-of the shift by means of an adjusting 'rin or nut 48 threaded on. the shaft, said nut ing received in a slot in the head 4?.
